| ( | x | − | 8 | ) | + | ( | x | − | 10 | ) | + | ( | x | − | 4 | ) | = | x |
| Left side of the equation = | x | − | 8 | + | ( | x | − | 10 | ) | + | ( | x | − | 4 | ) |
| = | x | − | 8 | + | x | − | 10 | + | ( | x | − | 4 | ) |
| = | 2 | x | − | 18 | + | ( | x | − | 4 | ) |
| = | 2 | x | − | 18 | + | x | − | 4 |
| = | 3 | x | − | 22 |
| 3 | x | − | 22 | = | x |
| 3 | x | − | x | = | 22 |
| 2 | x | = | 22 |
| x | = | 22 | ÷ | 2 |
| = | 22 | × | 1 2 |
| = | 11 | × | 1 |
| x | = | 11 |
